Description

Technical Field

[0001] This utility model relates to the field of thickener technology, and in particular to a multi-stage sludge scraping mechanism for a peripheral drive thickener. Background Technology

[0002] A thickener is a solid-liquid separation device based on the principle of gravity sedimentation. It typically consists of a shallow cylindrical tank with a conical bottom, used to precipitate and concentrate solid particles in a suspension and separate clear water. Its core function is to achieve solid-liquid stratification through sedimentation, increase the underflow concentration, and recover clear water. It is widely applicable for treating thick industrial slurries, such as coal, metal ore dressing water, metallurgical wastewater, and chemical slurries. The sludge scraping mechanism is a crucial component of the thickener.

[0003] The existing technology has the following problems: The existing thickener scraping mechanism has a relatively fixed structure and cannot adjust the scraper angle according to the change of sludge concentration. The fixed angle scraper is prone to sludge accumulation and slippage, requiring frequent shutdowns for cleaning. The scraping mechanism has poor adaptability and will also affect the efficiency and quality of scraping operation. To address these issues, we propose a multi-stage scraping mechanism for a peripheral drive thickener. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figures 1-7This utility model provides a technical solution: it includes a thickening tank 100, a control component is provided on the top of the thickening tank 100, the control component includes a support base 210, the support base 210 is fixed to the outside of the thickening tank 100, a support platform 220 is fixed on the top of the support base 210, a control cabinet 230 is provided on the outside of the support platform 220, a feeding component is provided at the bottom of the support platform 220, a drive component is provided on the top of the support platform 220, a sludge scraping component is provided on the outside of the drive component, the sludge scraping component includes a drive bracket 510, a mounting housing 520, a mounting shaft 530, a connecting plate 540, a damping rod 550 and a scraper 560, and an adjustment component is provided on the outside of the mounting housing 520;

[0026] The adjustment assembly includes a motor mounting bracket 610, a servo motor 620, and a drive shaft 621. The drive shaft 621 is fixedly connected to a mounting shaft 530 in the middle section. Gears 630 are fixed to the outer sides of each of the mounting shafts 530. A pair of racks 640 are provided on the outer side of each gear 630. The racks 640 are slidably connected to a mounting housing 520. An angle sensor 650 is bolted to the side of the mounting housing 520 near the motor mounting bracket 610. Multiple adjustments are achieved through the cooperation of the scraping assembly and the drive assembly. The sludge scraping operation involves adjusting the scraping angle of scraper 560 according to the type and concentration of slurry during feeding. This adjustment allows for adjustment of the scraping angle based on changes in sludge, preventing sludge accumulation and slippage. This eliminates the need for frequent shutdowns for cleaning, ensuring the continuous operation of the thickener. During scraping, damping rod 550 provides buffer support for scraper 560, ensuring that scraper 560 remains in close contact with the inner wall of the thickening tank 100, thus improving the efficiency and quality of the scraping operation.

[0027] Specifically, a drain pipe 110 is fixed at the bottom of the thickening tank 100, and a control valve 120 is fixed on the outside of the drain pipe 110; the drain pipe 110 is opened by the control valve 120, and the sludge is discharged through the drain pipe 110.

[0028] Specifically, the feeding assembly includes a flow stabilizer 310, which is fixed to the bottom of the support platform 220 by bolts. A guide plate 320 is fixed to the inner wall of the flow stabilizer 310, and a feed pipe 330 is fixed to the outer side of the flow stabilizer 310. With the feeding assembly, the slurry enters the interior of the flow stabilizer 310 through the feed pipe 330, rotates and flows on the guide plate 320, and finally enters the interior of the thickening tank 100.

[0029] Specifically, a support block 331 is fixed to the outside of the feed pipe 330, and the support block 331 is fixedly connected to the support base 210; by setting the support block 331 to securely support the support platform 220, the stability of the feed pipe 330 during the feeding operation is ensured.

[0030] Specifically, the drive assembly includes a motor mounting base 410, the top of which is fixed to the support platform 220 by bolts. A geared motor 420 is fixed to the top of the motor mounting base 410 by bolts. A drive rod 430 is provided at the output end of the geared motor 420, and an installation sleeve 440 is fixed to the outside of the drive rod 430. By providing the drive assembly, the geared motor 420 drives the drive rod 430 to rotate, which in turn drives the installation sleeve 440 to rotate, thereby driving the scraper assembly to rotate, thus realizing the drive operation of the scraper assembly.

[0031] Working Principle: During operation, the thickener is controlled by the control cabinet 230. The slurry enters the stabilizing cylinder 310 through the feed pipe 330 and rotates on the guide plate 320 before finally entering the thickening tank 100. The reduction motor 420 drives the drive rod 430 to rotate, which in turn drives the mounting sleeve 440 to rotate, thereby rotating the scraping assembly and moving multiple sets of scrapers 560. The scrapers 560 perform multi-stage scraping operations. Before the scraping operation, the drive shaft 621 is rotated by the servo motor 620 at a certain angle according to the different types and concentrations of slurry fed in. The angle sensor 650 monitors the rotation angle of the drive shaft 621. For testing, the drive shaft 621 drives the mounting shaft 530 in the middle to rotate. The rotation of the mounting shaft 530 drives the gear 630 to rotate. Under the action of the rack 640, multiple gears 630 rotate synchronously, which in turn drives multiple scrapers 560 to rotate synchronously. This allows for adjustment of the scraping angle of the scrapers 560 according to the changes in sludge, preventing sludge accumulation and slippage. During the scraping process, the damping rod 550 provides buffer support for the scrapers 560, ensuring that the scrapers 560 always remain in close contact with the inner wall of the thickening tank 100. The discharge pipe 110 is opened by the control valve 120, and the sludge is discharged through the discharge pipe 110.
